Chapter: "Chapter on Wiping the Head of a Child." The hadith of Yusuf ibn 'Abd Allah ibn Salam (may Allah be pleased with them both)

The Shaykh : Now we have a new chapter, which also shows us a side of the hadiths we have previously covered in past lessons, from his saying (peace be upon him) From this mercy, Imam al-Bukhari was inspired and said in the chapter seventy-two after the hundred:
"Chapter on Wiping the Head of a Child".
Affection and love
He narrated with his authentic chain from Yusuf ibn 'Abd Allah ibn Salam, who said: .
'Abd Allah ibn Salam—there is no doubt among you regarding his biography or his story. He was one of the great rabbis of the Jews and one of the few who entered Islam. The Jews are a people of envy, meaning they are characterized by stubbornness and arrogance. Therefore, hundreds and thousands of Christians entered Islam, whereas the Jews entered only as individuals. This is from that small number. 'Abd Allah ibn Salam was among the rabbis and scholars of the Jews. When he met the Messenger (may Allah's prayers and peace be upon him), he believed in him and affirmed his truth. However, by his wisdom and knowledge, he wanted to reveal to the Prophet (peace and blessings be upon him and his family) the scheming and envy of the Jews. After he embraced Islam, immediately. 'Abd Allah did this to confirm to the Messenger (peace be upon him) what he knew of the Jews' scheming and envy.
This 'Abd Allah ibn Salam had a young son named Yusuf. Yusuf speaks about himself, saying that the Prophet (peace and blessings be upon him and his family) took him and placed him on his lap because he was small, and named him after one of the prophets, namely Yusuf (peace be upon him), and also wiped his head.
This wiping of the head of a small child—I know it in our land in Albania. It is a common practice, especially from my father (may Allah have mercy on him). He would hardly meet a small child without reaching out to his head, asking him, "How are you? May Allah bless you. How is your father?" and so on. This is one of the etiquettes of Islam, as you hear, but where is it now? It has absolutely no existence as a general etiquette, unfortunately.
As for small, related children, we still find some mention of it, but even then, it is within very narrow limits.
This hadith has a strong connection, as we mentioned earlier, to his saying (peace be upon him) Therefore, it is obligatory for the older man to show affection to the small child and to display his love and gentleness toward him, so that this small child grows up with an affection that inclines him toward the older man, to listen to his words and take his advice.
Finally, the author also brought another hadith indicating his (peace be upon him) etiquette with children and young girls. He narrates with his authentic chain:
From 'A'ishah, who said: .
This hadith requires much commentary, and perhaps the next lesson will have room for it, if Allah wills.
This is sufficient.
